platforms/rhesus/rhesus.c:126:6: error: variable 'pnor_chip' is used uninitialized whenever 'if' condition is true
      [-Werror,-Wsometimes-uninitialized]
        if (rc) {
            ^~
platforms/rhesus/rhesus.c:141:6: note: uninitialized use occurs here
        if (pnor_chip)
            ^~~~~~~~~
platforms/rhesus/rhesus.c:126:2: note: remove the 'if' if its condition is always false
        if (rc) {
        ^~~~~~~~~
platforms/rhesus/rhesus.c:121:30: note: initialize the variable 'pnor_chip' to silence this warning
        struct flash_chip *pnor_chip;
                                    ^
                                     = NULL
